Hi folks, I've lurked here for a long time (although still a hobbyist!) and am ready to ask a question! I'm using a Nikon D5000 with the 18-55 VR kit lens. I'm ready to both size up AND down, to get more distance out beyond what the kit lens offers (for landscape / architectural shots) and a macro lens for some detailed hobby work. I'm a hobbyist, no desire to turn into a professional photographer, so I'd like to keep it to a hobbyist level cost-wise (few hundred per lens at the most). Any suggestions?
